cross-coupling strategy that enables the direct arylation of carbonyl/iminyl derivatives in the presence of Et3N has been realized. Such an atom-economical protocol furnishes a broad scope of arylation products such as secondary/tertiary alcohols and amines via a PCET process that facilitates the challenging reduction of C═X (X = O, N). Mechanisticinvestigation indicates two photocatalytic redox cycles
